Anyone have Interior Squeeks and Rattles?

I lowered my car with the Tein H springs .09" in front & 1.7" in rear. The look is just what I wanted; right in the middle of both Eibach (SP?) springs. The car rides much firmer and feels great! However, I have noticed a few rattles and squeeks in the interior since I made the swap. Does anyone else that has lowered their car have the same issue?

I hear something like a spring tensioning either in the driver's seat or right around the driver's compartment. It only seems to happen while I am driving; I have tried reproducing the sound just sitting still but it never seems to do it. Something is tensioning while I drive and I can't figure out what it is.
